What does a ringed sealís breathing hole look like and how do you find one on a vast sheet of sea ice? Dr. Brendan Kelly uses the canine skills of Cooper, a Black Labrador he trained to chase the scent of ringed seals and point to their holes. Passionate about wildlife and climate change, Melanie Duchin has loaned her dog to work with Brendan for the past 5 years.

Alaska's coastal range is covered in literally thousands of thaw lakes. Ken Hinkel, Yongwei Sheng and John Lenters are embarking on a project to reveal the subtle energy dynamics that take place within these lake systems.

Join us as we celebrate the beginning of summer in the Arctic and the long, cold winter in Antarctica. We'll connect live to two polar field sites: Summit Camp atop Greenland's vast ice sheet, where the sun will be shining 24 hours a day, and the South Pole Research Station, now in the middle of 6 months of darkness.

Dr. Jewel Bennett, an endangered species biologist with the US Fish and Wildlife Service's Fairbanks field office, is in Barrow leading a survey team tracking the endangered Steller's and Spectacled Eiders' populations.

Inupiaq elders, local experts and scientific researchers partner on the North Slope to study and understand the changing environment. Wendy Eisner and Chris Cuomo join us to talk about their project: Indigenous Knowledge and Landscape in Northern Alaska.

In today's program Dr. Bart Kempenaers, a behavioral ecologist from the Max Planck Institiute of Ornithology in Seewiesen, Germany, talks about the research he and his team are doing on arctic breeding shorebirds in Barrow, Alaska.

Amanda Grannas' research group at Villanova University studies a wide range of topics under the umbrella of "analytical environmental chemistry", including the impacts of pollutants in the snow and ice. We'll chat with Amanda about her current research in the Arctic.

Join us for this special Webcast from Summit Camp, which sits atop nearly 2 miles (about 3200 m) of ice on the Greenland ice cap. We'll talk with Zoe Courville, an Ice Stories blogger and snow researcher from the Cold Regions Research and Engineering Lab, about life on top of an ice sheet. She'll also discuss her research into how snow becomes glaciers.

Dr. Vladimir Romanovsky is researching permafrost geophysics: the relationship between the frozen ground (permafrost) and climate. Join host Julie Konop as she asks Vladimir about his most recent data.
